Innovative conceptual design on a tracked robot using TRIZ method for passing narrow obstacles

Background/Objectives: One of the problems of tracked robots in ragged roads is to pass narrow obstacles. As a primary solution, the process of come back and pass another way is usually time consuming or impossible. Methods/Statistical Analysis: In this paper, first, we evaluate the usual solution for this problem, which is preparation of a drive system at the middle area and then by using of innovative problem solving method (TRIZ), by answering ISQ questionnaire and extracting some technical contradictions, we try to match them in contradiction matrix and finally by applying 40 innovative principles we solve these technical contradictions which lead us to the solution of the problem. Findings: Using this method, one innovative principal says, we can consent to pass partly narrow obstacles and for very narrow ones we can find another solution. Another principal says, existing elements can do the duty of new elements and for it flippers location can be changed from outside of driving tracks to inside of them and make universality for flippers. In the other hand Using flippers and middle dive system separately causes when one of them is in service the other become out of service. Applications/Improvements: Using such a system without adding any new element when responding all requested functions means that "ideality degree of system increased".
